IR123PRSG Specifications, Features & Compatibility Guide
IR123PRSG delivers 3450W cooling via flexible Convertible technology for harsh Indian summers. Pure 1 Ton capacity achieves 3.96 ISEER using 674.08 kWh annual power consumption with R32 refrigerant gas.
Quick Answer
Yes, the IR123PRSG is a compelling purchase for efficient cooling. Perfect for 90-130 sq.ft rooms, it boasts a BEE 2023 3 Star rating and ISEER 3.96 for significant energy savings. Its 100% copper condenser and R32 refrigerant ensure durable, consistent performance even in India's high ambient temperatures. Opt for the IR123PRSG to gain reliable comfort and lower long-term operational costs.
If your space is 90-130 sq.ft and you prioritize verified energy efficiency (ISEER 3.96) for long-term savings, the IR123PRSG is your ideal choice. However, avoid if your cooling area exceeds this capacity or if initial capital cost outweighs the benefits of its 3 Star performance.
✓ Who Should Buy
- •1 Ton 3 Star performance suitable for 90-130 sq.ft spaces.
- •Verified efficiency of 3.96 for reduced long-term operational costs.
- •Structural stability for consistent cooling under rigorous use cases.
- •Hardware durability via Copper coil and R32 technology.
- •Built-in grid protection with Standard power cycle voltage management.
✕ Who Should Avoid
- •Spaces or usage requirements exceeding 90-130 sq.ft rated capacity.
- •Installations prioritizing minimum capital expenditure over 3.96 performance.
- •Unstable grid conditions exceeding the functional threshold of Standard power cycle.
- •Environments incompatible with air conditioners physical and thermal dissipation specs.
Product Overview
Delivering a rated cooling output of 3450W, the IR123PRSG is a 1 Ton 3 Star Inverter Split air conditioner purpose-built for rooms up to 90-130 sq. ft. in India's high-ambient-temperature climate. Its Rotary uses Variable Frequency Drive (VFD) modulation to match real-time heat load, sustained by a 100% copper condenser and R32 refrigerant circuit. BEE 2023 ISEER of 3.96 positions it among the most economical models in the 1 Ton segment, with annual consumption of 674.08 kWh. 5-in-1 Convertible mode flexibility allows tonnage adaptation for varying seasonal load. Certified for operation up to 55°C, this Inverter Split AC handles India's peak summer intensity without compressor thermal stress.

Engineering Analysis
Energy performance of the IR123PRSG is anchored by its BEE 2023 3 Star certification and an ISEER of 3.96. Under standardised BEE test cycles, annual consumption is 674.08 kWh per year — competitive long-term operational cost over a 5-year ownership horizon. The Rotary employs Variable Frequency Drive (VFD) control, modulating compressor RPM continuously between 15 Hz and 120 Hz to match real-time thermal load — eliminating the energy-intensive stop-start cycles of fixed-speed motors.
The IR123PRSG is built around 100% copper condenser coils, which outperform aluminium alternatives with 40% higher corrosion resistance — a critical durability metric for India's coastal zones, humid interiors, and regions with salt-laden particulate air. Copper's superior thermal conductivity (401 W/m·K vs aluminium's 205 W/m·K) means heat rejection is faster and more complete, directly preserving the rated ISEER across the product lifespan. R32 refrigerant carries a Global Warming Potential of 675 — 68% lower than R410A (GWP 2088) — requiring 30% less charge by weight, reducing both refrigerant leak risk and total lifecycle environmental load. Multi-stage filtration (Dust) captures PM2.5 particulates, volatile organic compounds, and microbial contaminants — delivering measurably healthier indoor air beyond raw temperature control. 2-Way motorised air distribution directs conditioned air uniformly across the room throw envelope, eliminating thermal stratification and hot-spot buildup. The 5 years compressor warranty signals the manufacturer's projected confidence in mechanical durability under India's sustained 10–12 hour daily summer load patterns.
Standard power management rated at 230V ensures safe operation. Auto-restart with non-volatile memory ensures the IR123PRSG resumes at the last-set temperature and mode after power interruption — a functional reliability requirement for Indian grid zones experiencing 4–10 daily outages during peak summer months. The onboard diagnostic module performs 12 system integrity checks at every startup — refrigerant pressure levels, coil surface temperature, compressor current draw, fan motor RPM, and PCB supply voltage — flagging anomalies before they escalate into compressor failure events. Validated for 55°C maximum ambient operation — 7–9°C above the IEC 60335-2-40 standard test baseline of 43°C — the hardware thermal management stack is certified for India's harshest summer regions including Rajasthan, Vidarbha, coastal Andhra Pradesh, and the Gangetic plains.
